Official cycle & ovulation tracking app of Taking Charge of Your Fertility (TCOYF), co-founded by Toni Weschler, MPH. Carefully crafted by Toni Weschler, MPH - renowned Fertility Awareness Method (FAM) expert and author of the best-selling book Taking Charge of Your Fertility - alongside a passionate team of product designers, developers and physicians, the goal of Cyclisity is simple: be the world's best symptothermal method tracking app. Integrating seamlessly with the 2015 edition of Taking Charge of Your Fertility, Cyclisity follows TCOYF's science-based guidelines to help you confidently track your ovulatory cycles and practice FAM. Because a strong knowledge-base is crucial to practicing FAM correctly, in-app references can guide you back to key educational concepts from the book, ensuring you have ample support on your fertility awareness journey. PAID FEATURES: * Two tracks to choose from (Ovulation and Period Tracking or Pregnancy Achievement) * Ovulation and period tracking chart and calendar * Auto-detection of peak days and coverlines even for tricky thermal shifts (Runs all TCOYF rules automatically, so you can check your work) * Book references to TCOYF at helpful points throughout the app * Community forums rooted in learning and support * More features like charting secondary fertility signs and thermometer integrations coming soon! NO PREDICTIONS. Every woman's ovulatory cycle is unique. That’s why we don’t use predictive algorithms to guess at your fertile window. Instead, we help you chart your waking temperature, cervical fluid, and cervical position, and seamlessly apply the four FAM rules each day as taught in Taking Charge of Your Fertility. No shortcuts. No rhythm method. Just science, your observations, and the tools to help you read them with confidence. YOUR PRIVACY IS OUR COMMITMENT.
